oa Annals of the Natal Museum - A revision of the southern African Scissurellidae (Mollusca: Gastropoda: Prosobranchia)

Volume 27, Issue 2
  • ISSN : 0304-0798



Southern African Scissurellidae were investigated using SEM. Nine species (three new) of the genera Anatoma, Scissurella, Sinezona and Sukashitrochus are discussed. Reasons for elevation of Anatoma to full generic status and for recognition of Sukashitrochus are given. Scissurella and Sinezona are thought to be closely related. Comments on anatomy and biology are made; radular morphology and protoconch sculpture are considered of taxonomic significance. New species: Anatoma yaroni, Sinezona doliolum and Sukashitrochus maraisi. New synonyms: Scissurella jucunda Smith, 1910 and S. smithi Thiele, 1912 = S. jucunda Smith, 1890. New combinations: Scissurella agulhasensis Thiele, 1925, and S. tabulata Barnard, 1964, are transferred to the genus Anatoma. New record for southern Africa: Scissurella rota Yaron, 1983, descriptionbed from the Red Sea. Radula figured: Anatoma yaroni sp. n. Scissurella minuta Turton, 1932, is not thought to be a scissurellid and is regarded as a nomen dubium.
